----------------------------------------
Summary: enable use of python's "with" statements for SparkContext
management
Key: SPARK-3458
URL: https://issues.apache.org/jira/browse/SPARK-3458
Project: Spark
Issue Type: New Feature
Components: PySpark
Reporter: Matthew Farrellee
best practice for managing SparkContexts involves exception handling, e.g.
```
try:
sc = SparkContext()
app(sc)
finally:
sc.stop()
```
python provides the "with" statement to simplify this code, e.g.
```
with SparkContext() as sc:
app(sc)
```
the SparkContext should be usable in a "with" statement
